Dear all, how can I bring the backfill scheduler to examine all low-priority jobs for possible execution?
We have situations with >100000 jobs and times with just a few hundreds. So a fixed bf_interval does not make sense. Is there some option to say the bf scheduler runs down to the bottom of the queue an then starts at the top, just ignoring bf_interval. As a workaround, I now have a python script checking sdiag (via API). If "Last depth cycle" is much smaller than "Last queue length" I increase bf_interval by 50% (+ scontrol reconf) - and the other way round comparing the bf cycle time with bf_interval. This works but I would assume something built-in in Slurm - though I haven't found it, yet.
